CONFIG_FLASH_LOAD_SIZE¶

Kernel load size

Type: hex

Help¶

If non-zero, this option specifies the size, in bytes, of the flash area that the Zephyr image will be allowed to occupy. If zero, the image will be able to occupy from the FLASH_LOAD_OFFSET to the end of the device.

If unsure, leave at the default value 0.
